I answered this question by userFlorin Simion:

I want to redirect users to a different page when they’re not connected to the Internet.

My only question is why this is working:

if (window.Connection) {
    if(navigator.connection.type == Connection.NONE) {
        alert("Please connect to internet");
    }
}

and this is not

if (window.Connection) {
    if(navigator.connection.type == Connection.NONE) {
        $scope.state.go('offline');  
    }
}

My answer was:

Because you’re using $state the wrong way. Instead of this:

$scope.state.go('offline');

You should do it like this:

$state.go('offline');

Remember to inject $state in your controller. More information about $state from official docs.

By “Remember to inject $state in your controller” I’m referring, for example, to this:

app.controller('ctrl', function ($scope, $state) {
    $scope.changeState = function () {
        $state.go('someplaceNice');
    };
});

I answered this question by user user1365697:

We want to build a simple application that use a lot of videos and images. The application should run on different mobile devices running Andriod and iPhone operating systems. Does Ionic also convert each application to all mobiles options? What do you suggest to use Cordova or Ionic?

My answer was:

Disclamer: This will sound like advertisement, so I have to say I’m in no way affiliated with Ionic, I just happen to like it so much that I’m sharing the love for it.

Ionic is so much more than “just” an UI framework. Ionic allows you to:

• generate icons and splash screens for all devices and device sizes with a single command: ionic resources. This alone saves you at least a day of image preparing for various sizes.
• instantly update your apps with code changes, even when running directly on your device with ionic run --livereload
• build and test iOS and Android versions side-by-side and see changes instantly with ionic serve --lab
• share your Ionic apps with clients, customers, and testers all around the world without ever going through the App Store with ionic share
• easily accessing the full native functionality of the device using ngCordova (here you get to use any Cordova plugin – so Ionic is indeed much more than Cordova per se)

Also, they’re building a full-stack backend services and tools for your Ionic app like Deploy (for deploying a new version without going through Apple review process!), Analytics, Push notifications.

Ionic CLI (command line interface) uses Cordova in the backend and allows you to build (directly using Ionic CLI) apps for iOS and Android (you by doing ionic build ios or ionic build androidand woila).

Ionic uses Angular as a frontend framework so if you’re familiar with it it will come as a bonus. They’reworking closely with the Angular 2.0 team too.

All in all, I personally think Ionic has a bright future, so if nothing else – give it a try I bet you’ll like the ease of making an app with it.

Recently I was reinstalling ionic and cordova with:

npm install -g cordova ionic

but I got the following error:

    E:\IonicTesting>npm install -g cordova ionic

At first I thought the reason is that I may have had an older version of node or npm but wasn’t the case because my versions were up to date (date of this post: 03.08.2015):

E:\IonicTesting>node -v
v0.12.7

E:\IonicTesting>npm -v
2.11.3

Also, I did try:

npm update -g

and

npm cache clean

as noted in the few StackOverflow answers, but it didn’t help. After a bit of googling and messing around I realized (an idea came from this StackOverflow answer) that I could try uninstalling the dependencies which were messing with me:

npm uninstall -g node-inspector
npm uninstall -g strong-cli
npm install -g generator-karma

After this I ran

npm update -g

and then, to finally install Ionic and Cordova, I ran:

npm install -g cordova ionic

And, what do you know – it worked. Hope this helps someone!

As you may know, CodeProject has a thing called Technical blogs which lets you publish your post on their site too, and thus widening the range of potential readers.

Thanks to a great plugin by hjgode you can automatically import your posts.

However, recently I wanted just to show excerpts of the posts on my blog homepage and in the archives. The problem was that that stopped the importer from collecting the posts that are marked with the codeproject category because the posts were too short according to their rules (1000 words minimum).

I solved this in my  TwentyThirteen theme by doing slight changes in content.php (around line 33), which by default looks like this:

<?php if ( is_search() ) : // Only display Excerpts for Search ?>

This line displays excerpts only on a search page, and to show excerpts on homepage I did:

<?php if ( is_search() || is_home() ) :  ?>

You just have to make sure that you don’t include the

is_category()

and you’re all set.

True, you could further optimize this in a way that you would show excerpts for all other categories except “codeproject”.

I actually answered this question by userArlind a:

I’m using AdMob plugin in Ionic and with this code I show an Interstital ad:

function initAd(){

 // it will display smart banner at top center, using the default options
 if(AdMob) AdMob.createBanner( {
                          adId: admobid.banner,
                          bannerId: admobid.banner,
                          position:AdMob.AD_POSITION.BOTTOM_CENTER,
                          autoShow: true,
                          isTesting: false,
                          success: function(){
                          console.log('banner created');
                          },
                          error: function(){
                         console.log('failed to create banner');
                          }
                          } );

                                       window.AdMob.prepareInterstitial( 
                           {adId:admobid.interstitial, autoShow:false} );
    window.AdMob.showInterstitial();

 }

Is there a way to show intersitial ad every 2 minutes? Someone told me to add this:

setInterval(showInterstitial,1*60*1000)

but I don’t know where to add?

My answer was:

If you would like to show it every 2 minutes you should use:

setInterval(window.AdMob.showInterstitial, 2*60*1000);

and you should add it just before the closing bracket of your initAdd function:

function initAd(){


 // it will display smart banner at top center, using the default options
 if(AdMob) AdMob.createBanner( {
                          adId: admobid.banner,
                          bannerId: admobid.banner,
                          position:AdMob.AD_POSITION.BOTTOM_CENTER,
                          autoShow: true,
                          isTesting: false,
                          success: function(){
                          console.log('banner created');
                          },
                          error: function(){
                         console.log('failed to create banner');
                          }
                          } );

                                       window.AdMob.prepareInterstitial( 
                           {adId:admobid.interstitial, autoShow:false} );
    window.AdMob.showInterstitial();
  
  
  
  //!!!add the code here!!! - so, just paste what I wrote above:
  setInterval(window.AdMob.showInterstitial, 2*60*1000);

 }

You can see a simple setInterval usage on this jsFiddle example:

function a(){
    alert("hi every 2 seconds");
};

setInterval(a, 2*1000);

The reason why you shouldn’t call it like this (note the brackets after a): setInterval(a(), 2*1000); is that then your function would be called only once (you would see only one alert popping up). Example on jsFiddle:

function a(){
    alert("hi every 2 seconds");
};

setInterval(a(), 2*1000);

My notes from the book Choose Yourself! by James Altucher:

Learned man aims for more, but the wise man decreases, and then decreases again.

The thing that really matters in this world are relationships you have with people you love and meaningful things that you do. Haters don’t fit anywhere into that.

• Sleep eight hours
• Eat two meals instead of three (I don’t agree with this one personally )
• No TV
• No junk food
• No complaining for one whole day
• No gossip
• Return an email from five years ago
• Express thanks to a friend
• Watch a funny movie
• List down a bunch of ideas
• Read spiritual text
• Say to yourself in the morning “I’m going to save a life today”
• Pick up a hobby
• Surprise someone
• Think about five people you’re grateful for
• Forgive someone – write it on a paper and burn it
• Take the stairs
• Don’t see yes when you think no
• Tell someone you love them
• Deep breathing

After a certain salary point, your marginal happiness doesn’t go up.

Writing a book never really makes a lot of money, but there are all these additional benefits of writing a book: consulting, speaking, TV shows, ghost writing, email list to market further. 

In order to get good ideas read two hours a day and write ten ideas a day.

Wake up and think of five people you’re grateful for.

Meditation – don’t time travel, be in the present.

Negotiation is worthless, sales is everything.

Better to sell early than to go broke.

Simple effort will give you a customer for life – always give a little extra. 

If you love something you get knowledge, the contacts, you’ll build something nobody else has, you’ll wow the customers.

… and that’s Stephen King – all it took was a few weeks of not writing to fall completely off his game even though he’s one of the best in the world at what he does.

The idea muscle has to be exercised daily.

Activate another part of your brain. Best ideas come from collision between  newer  and older ideas. Take two older, unrelated ideas and make them have sex.

Perfectionism may harm you. Embrace failure and get ASAP on your feet again.

Delegate jobs to someone else.

If you can’t help yourself you won’t be able to help others.

Be physically, emotionally, spiritually and mentally healthy.

My question was:

The problem I’m facing, as outlined in the code, is that I can’t seem to find out how to bind the second checkboxes (created with ng-repeat) to some model which I would then be able to use further down the code (showing/hiding yet another set of options). Also, I managed to show the additional number of inputs based on the count parameter in the $scope.availableOptions by using the $scope.getItterator function, but now I don’t see how would I access the values of these checkboxes? I know I have to somehow use the option “ng-model” but am failing to do so, so any help appreciated.

My code is here, but am showing it here too:

HTML:

<div ng-controller='MyCtrl'>
    Show additional options <input type="checkbox" ng-model="additionalOptions">
    <div ng-show="additionalOptions">
        <ul>
            <li ng-repeat="option in availableOptions">
                <label class="checkbox" for="opt_{{option.id}}">
                    <input type="checkbox" name="opt_{{option.id}}" id="opt_{{option.}}" />
                    {{option.name}}

                    <ul ng-show="if the upper checkbox is clicked">
                        <li>
                            <input type="text" ng-repeat="i in getItterator(option.count)" ng-model="SOME_VALUE_TO_BE_USED_BELOW"/>
                            Output the value based on what's entered above in the textboxes (SOME_VALUE_TO_BE_USED_BELOW)
                        </li>   
                    </ul>
                </label>
            </li>
        </ul>
    </div>
</div>

and my js:

function MyCtrl($scope) {
    $scope.availableOptions = [{"id":"1","name":"easy","count":"2"},{"id":"2","name":"medium","count":"3"},{"id":"3","name":"hard","count":"2"}];

    $scope.getItterator=function(n){
        var a = new Array();

        for(var i=1; i <= n; i++)
            a.push(i);

        return a;       
    };
}

The answer, by user Khanh TO, was:

Try ng-model="option.checked":

<input type="checkbox" name="opt_{{option.id}}" id="opt_{{option.}}" ng-model="option.checked"/>

And then you can access this property further below like this:

<ul ng-show="option.checked">

DEMO

If you need to also reference the text box inputs. You create a new property (values) on the option. Like this:

{"id":"1","name":"easy","count":"2",values:[]}

Html:

<div ng-repeat="i in getItterator(option.count)">
     <input type="text"  ng-model="option.values[$index]"/>
      {{option.values[$index]}}
</div>

When I was preparing this post I bought a domain just for testing purposes called nikola-dev.com and I wanted to have Node.js apps running on this VPS (behind a NGINX running as proxy) but that they would be accessible from different domains (for example mean.nikola-dev.com). Below are the steps I needed to take in order to make this happen:

1. Clearly, have a droplet on DigitalOcean
2. Buy a domain (where ever you buy it, make sure you use Honey, to get the best price)
3. Edit the Nameserver information in the admin dashboard of your domain provider (where you bought the domain) to the following three records:
   ns1.digitalocean.com, ns2.digitalocean.com, ns3.digitalocean.com
4. Add the domain on DigitalOcean DNS settings page:
   
5. Delete /etc/nginx/sites-enabled/default
6. Create /etc/nginx/sites-available/nikola-dev.com file with the following content (this will be a simple single HTML file which will list the available test apps on this server):

   server {
       listen 80;
       server_name nikola-dev.com;
       root /var/www/nikola-dev.com/public_html;
   }

7. Create /etc/nginx/sites-available/mean.nikola-dev.com file with the following content (this will serve the actual Node.js app that we’re building in this tutorial):

   server {
       listen 80;
   
       server_name mean.nikola-dev.com;
   
       location / {
           proxy_pass http://127.0.0.1:3000;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection 'upgrade';
           proxy_set_header Host $host;
           proxy_cache_bypass $http_upgrade;
       }
   }

8. Restart NGINX:

   sudo service nginx restart

Clearly, if you would need to add more subdomains, just repeat the steps from step 6 onward. Of course, you would need to put your other Node.js apps on different ports, since only one app can work on one port.

My notes from an awesome book EDGY Conversations by Dan Waldschmidt, which I rated 5/5 on my Shelfari account:

Success is not about what you do, it’s about what you are.

Who and what do you want to be, and why?

Van Gogh sold only one picture during his lifetime.

You have to look within yourself and challenge the demons that hold you back from being successful.

You’ll never rise to be a champion if you can’t pass the fear and the failure and the excuses holding you back.

You have to believe that you can be amazing regardless of where or who you are right now.

Carl Sugarfoot Joseph

Simply getting up one hour earlier a day for 50 years equates to an extra 2281 business days, or 6.25 years of conquest.

You win more when you fight more.

Success is an attitude: don’t be afraid to be extreme, be disciplined, be giving, understand the why human factor.

Are you willing to commit to extreme behavior? When you decide that it’s going to be hard. When you know that you have to outwork, outthink, outplay, outmuscle everything you do from this day forward extreme behavior actually becomes a great way to focus what you do.

Small jump forward is actually a big leap backwards.

You want harmony, not balance.

People really want to believe effort is a myth. I think we’ve been tricked by the few lucky people on the top of the heap. We see the folks who managed to get by and it’s easy to forget that these guys are the exceptions. For everyone else effort is directly related to success. You don’t get to choose luck, effort on the other hand is available there all the time.

Jerry Rice

Only limits that exist are the ones in your head.

With discipline and effort you can do just about anything.

The average age of a successful interpreter is mid 40s.

Effort is more than ‘if you pay me more, I’ll work harder’, it’s about not cheating yourself out of your potential.

Cliff Young

Passion is the antidote to the setbacks you will surely face on the way to success. It’s that often illogical passion and emotion that allows you to keep going long after it makes sense. When you put enough of yourself into something you will do whatever it takes to come out as a winner.

Anyone can conquer when the odds are in their favor. The challenge is to do what it’s hard and the noble and the right when you are sick and tired and tired and sick.

It takes discipline to keep moving forward.

It’s not only what you’re willing to do what will make you successful, it’s also what you’re willing to do without, until you get there.

You may spend a decade of sleepless nights until you make it to the finish line – and you need to plan for that.

Plan to work harder than you ever imagined possible. And then, double that effort!

Your plan should be bigger than simply “not losing”.

Have a giving mindset.

Success and living in balance life should not be in the same sentence.

Give expecting nothing in return, and you will change people’s lives.

Marianne Williamson: “Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness, that most frightens us. We ask ourselves, who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? You are a child of God. Your playing small doesn’t serve the world. There’s nothing enlightened about shrinking so that other people won’t feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It’s not just in some of us; it’s in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we’re liberated from our own fear, our presence automatically liberates others.”

Derek Redmond

Brain handling new information: If it’s boring or expected, brain ignores it. If it’s too complex, the brain dramatically summarizes it. If it’s threatening it prepares for “fight or flight” scenario.

What do you think about most is what you become. You are today who you thought you would be. You will be in the future who you think you want to be today.

Everything in life starts with your thinking. If you let fear drive your thoughts, you’ll never do the things that lead to success. You’re actually a lot stronger than the fear in your mind lets you think you are.

If you want to dominate, control your thoughts.

Successes is what you decide it is, not what other people tell you it should be. You decide what is right for you.

You,  believe in you…
